the previous owner got a new dryer so I don't need that. the compressor is compatible with r134a so I'm okay there as well. I do have to remove the compressor and the PAG oil and refill it with the compatible oil.
I saw that some people were getting the conversion kit for around $100.
Oh, that sucks. Well I'm not sure what else you need so I asked a guy on an e30 forum who has done it before. I'll get back to you on this. It seems like all you may need is just new o-rings.
